Abstract
An optical fiber sensor, disposed in the insulation of a wire or cable, provides a means of detecting damage to the insulation of the wire or cable. An optical measurement device, such as an optical time domain reflectometer (OTDR), coupled to the sensor, detects the presence and location of a sensor fault or stress. The sensor is positioned between the conductor and the outside surface of the conductor so that the OTDR will sense damage before the conductor is exposed or contacted by a damage element.
